Most of the hid sensor field size is reported in report_size field in the report descriptor. For rotation fusion sensor the quaternion data is 16 byte field, the report size was set to 4 and report count field is set to 4. So the total size is 16 bytes. But the current driver has a bug and not taking account for report count field. This causes user space to see only 4 bytes of data sent via IIO interface. The number of bytes in a field needs to take account of report_count field. Need to multiply report_size and report_count to get total number of bytes.
